As a certified reference material (CRM), 11-Chloroundecanoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
11-Chloroundecanoic acid (CAS 1860-44-2), molecular formula C11H21ClO2 and molecular weight 220.74 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 11-Chloroundecanoic acid (C11H21ClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
